Dog therapy reduces stress

The scientific evidence on the benefits of contact with dogs in clinical settings has consolidated over the past decade. Studies published in journals such as Frontiers in Psychology and AERA Open documented measurable reductions in cortisol, the stress hormone, in university students who interacted with dogs during exam periods. Oxytocin, associated with social bonding and anxiety reduction, increases consistently in both people and dogs during physical contact.

Animal-assisted therapy programmes in hospitals began experimentally in the 1970s and 1980s, but expanded significantly once empirical evidence exceeded anecdote. Today they exist in paediatrics, where they reduce perceived pain during medical procedures; in oncology, where they improve the mood of patients undergoing treatment; and in mental health, where they complement psychotherapy in the management of post-traumatic stress.

The logistics are not trivial. Therapy dogs require specialised training and certification, and hygiene protocols in clinical settings are strict. Organisations that provide these services, such as Animal Assisted Intervention International, establish standards that include temperament assessments, vaccination and rest schedules for the animals. The animal's welfare is an integral part of the protocol, not just the patient's. The results justify the investment: the costs of a canine therapy programme are marginal compared to the measurable benefits in recovery and well-being.
